Calculating the Sum of Measurements

To calculate the sum of the given measurements, we can add them together. The given measurements are: - 1 meter 7 decimeters 6 centimeters - 2 decimeters 9 centimeters

Conversion of Measurements

First, let's convert all the measurements to the same unit for easier addition.

1 meter 7 decimeters 6 centimeters can be converted to centimeters as follows: - 1 meter = 100 centimeters - 7 decimeters = 70 centimeters - Total = 100 cm + 70 cm + 6 cm = 176 centimeters

2 decimeters 9 centimeters can be converted to centimeters as follows: - 2 decimeters = 20 centimeters - Total = 20 cm + 9 cm = 29 centimeters

Sum of Measurements

Now, we can add the converted measurements together: - 176 centimeters + 29 centimeters = 205 centimeters

So, the sum of 1 meter 7 decimeters 6 centimeters and 2 decimeters 9 centimeters is 205 centimeters.
